ute animals belong on the short list of subjects that will likely remain popular online until the end of humanity as we know it. While cats still remain a dominate force in this area, other animals have made enormous strides in competing for our attention online.

Advice animals are becoming less culturally relevant with each passing year, but the Seal of Approval series saw a significant boost in popularity on Reddit. Additionally, the photoshop meme Overly Excited Dog made its debut on /r/aww, where Redditors share the most disgustingly adorable photographs they can find.

In France, an animal rights group were caught on camera stealing a puppy from a homeless man, causing an enormous backlash on the French web. Additionally, French activists from the Bird Protection League drew the ire of a shovel-wielding man in his underwear, launching the infamous Slipgate photoshop meme.
